This should do it:
Here you go, as near to step-by-step as I can do it. We’ll first search for the location of your Audacity program; then look at the cluster of Audacity folders with Windows Explorer; put the Lame file in a suitable place; then tell Audacity where to look for it.
Left click on the Start button at bottom left of the desktop, choose Search, then slide your cursor over “Files and Folders” and left click
First, in the menu across the top of the search box, click on View, then click on Details in the pull-down menu that appears (this is so you can see what type of files you are looking at when you carry out your search).
Under “What do you want to search for?” click on “all files and folders”
In “All or part of the file name” type “audacity” (without the quote marks), then click on Search at the bottom of that dialog box. (“Look in local hard drives C:” should be showing in a box a little below the File Name box.)
The results of the search appear to the right. One of the files should be “audacity.exe”. Make a note of its location, which should be to the right (on my machine, it is C:\Program Files\Audacity. This is the folder where your program is hiding.
Close the Search box by clicking on the X at top right.
Display the Audacity folders:
Left click on Start, slide the cursor to Programs; then within the programs list (probably right at the top), slide up to Accessories; then within the next menu, slide the cursor down to Windows Explorer and click on it.
This should open up two windows next to each other. The left one shows the folders on your computer, and the right one shows you what’s in any one of those folders that you click on.
First, in the left window, click on Desktop …. I think that’s where your Lame files were unzipped? (including lame_enc.dll) .. just to make sure you’ve got it: it should appear in the window on the right. If the right window is full of icons, click on View in the menu bar at the top, and select Details again, to see more information about the files.
(If it’s not there, come back and ask again!)
Then, in the right window …. hold down the control key and left click on all the files with lame in their file name. They should now all be highlit. Now Right-Click on one of these and choose Cut from the menu. This stores them, ready to be put in their new location.
Now you’re going to navigate your way down through the tree of folders: in the window on the left, click on the little “+” symbol next to “My Computer”; then click on the “+” next to “Windows (C:)”. This shows the main folders on your hard drive. Remembering the location of the Audacity program that you made a note of earlier, click on the + ‘s until you get there.
On my machine (and yours is likely to be the same), under C: there’s a + labelled “Program Files”. Clicking on this lists the folders holding all the different application programs. Clicking on the Audacity + gives four more folders, one of which is Plug-ins. (This is where your Lame files are going to go.) Make a note of the sequence of folders that you’ve gone through … in my case C:\Program Files\Audacity\Plug-ins
Now in that left window, Right-Click on the name Plug-ins. It will become highlit and a menu will open up. Choose Paste from the menu. All those Lame files will now be pasted into the Audacity Plug-ins folder.
Now Close Windows Explorer with the X at top right.
Tell Audacity where the lame_enc.dll file is:
Open Audacity (by clicking on its Desktop icon). Click on Edit in the menu at top, and click on Preferences in the pull-down. Then in the box that opens, there is a line of tabs across the top. Click on the one labelled File Formats. In the page that opens, part way down on the right is a button labelled Find Library (within an outlined box labelled “MP3 export set up”.)
Click on the button. You’ll get a little message asking if you want to locate your lame_enc.dll file. Say yes. Now, from the little pull down at the top, work your way down the folders until you get to the Audacity Plug-ins folder. The file should be displayed. Click on the Open button. Then close down the various windows. Audacity should now be able to export mp3s.
